Drum-type filtering device

Abstract

The invention provides a drum-type filtering device. The drum-type filtering device comprises a drum wheel, a filter belt, a driving roller device, a back-flushing device, a soiling solution return pipe, a detection switch, a scraping device, a residue filter tank, a purified liquid tank, a brushing roll and a device main body, wherein a soiling solution flows into a cavity of the drum wheel through the soiling solution return pipe, liquid is filtered by virtue of the filter belt and flows into the purified liquid tank for being machined by a machine tool, impurities in the soiling solution are blocked by the filter belt and are continuously settled to form a filter cake, after the filter cake is accumulated to a certain thickness on the surface of the filter belt, the filter belt rotatesalong with the driving roller device, and the filter belt with the surface attached with the filter cake part rotates outwards, so that the cycle use of the filter belt is realized; meanwhile, the device is further provided with the scraping device, a drying device and the like, so that the filter cake can be removed and dried; and the device has the advantages of good filtering performance, reliability in operation, simple and compact structure, low maintenance cost and the like, and the cycling filtration can be realized.

Description

technical field [0001] The invention belongs to the field of machine tool processing, in particular to the precise filtration of cutting fluid in the field of machine tool processing, and in particular to a drum filter device.

Problems solved by technology

[0002] In the case of high-precision machine tools or high precision parts machining, the cleanliness of the cutting fluid used is also required to be high, so it is necessary to carry out precise filtration of the cutting fluid. A filter and paper tape filter equipment, the filter is usually composed of a cylinder, a stainless steel filter, a sewage part, a transmission device and an electrical control part. After the liquid to be treated passes through the filter cartridge of the filter screen, its impurities are blocked. When cleaning is required, the detachable filter cartridge needs to be taken out and reinstalled after treatment. However, the filter has problems such as low filtration capacity, regular cleaning and replacement of the filter element, time-consuming and labor-intensive problems. The principle of paper tape filtration is to use Industrial filter paper for filtration refers to a filtering method that passes cutting fluid or grinding fluid through industrial filter paper, isolates impurities on the industrial filter paper, and clean liquid enters the water tank through industrial filter paper. However, industrial filter paper is disposable. Consumables, very expensive to use
